HUMIDIFIER FOR INTERNAL-COMBUSTION ENGINES.

Application filed May 20, 192 1.

T 0 all whom it may concern:

Be it known that I, FRED L. MGNEILL, a citizen of the United States, residing at Annawan, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in a Humidifier for Internal-Combustion Engines, of which the following is a specification.

This invention relates to new and useful improvements in attachments for internal combustion engines and has for its principal object to provide a humidifier in connection therewith whereby the efficiency in the explosion of the charge from the carburetor and the intake manifold to the engine will be increased.

Another object of the invention is to provide a humidifier attachment of the above mentionedcharacter, wherein means is pro vided for supplying moistened air to the carburetor, means being further provided for supplying a quantity of the moistened air to the intake manifold.

A further object of the invention is to provide a humidifier attachment of the above mentioned character, which is simple in construction, inexpensive, strong and durable and. furthermore adapted for the purposes for which it is designated.

Other objects and advantages of this invention will become apparent during the course of the following description.

In the accompanying drawing forming part of this specification and in which like numerals designate like parts throughout the same:

Figure 1 is a side elevation of an internal combustion engine showing my humidifier attachment in position thereon.

Figure 2 is a side elevation of the fitting forming a part of the present invention with parts broken away, and

Figure 3 is a vertical section taken approximately on line 38 of Figure 1.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates an internal combustion engine of any well known construction and includes the usual intake manifold 2, the carburetor 3 which is connected to the intake manifold, the radiator 4 and the connection 5 between the radiator and the forward end of the internal combustion engine. My humidifier attachment comprises a casing, the bottom of which is provided with a depending tu- Serial No. 714,628.

bular extension 7 for the purpose of enabling the casing to be supported on the neck 8 of the radiator 4t.

The upper end of the casing is open and is provided with the external screw threads thereon for detachably receiving the closure cap 9 in the manner as is obvious from the construction shown more clearly in Figure 3. Extending vertically through the casing 6 and arranged centrally therein is the cop-' per tubing 10. The upper end of the tube extends slightly above the upper edge of the casing while the lower portion of the tube within the casing extends through the tubular extension 7 and the neck 8 of the radiator and through the upper rear portion of the radiator and the connection 5 between the radiator and the forward end of the internal combustion engine.

A fitting such as is shown at 11 is disposed between the internal combustion engine and the adjacent end of the connection 5 forming a connection between the conduit 5 and the engine, the same being further provided with a central opening 12, whereby the water from the radiator may pass into the internal combustion engine water acket. The fitting is further provided with opening 13 in the ends thereof for receiving the usual fastening bolts 1 1 in the manner well known in the art. The fitting 11 is provided with a depending tubular extension 15 and the purpose of this construction is to provide a means whereby the copper pipe 10 which extends from the upper rear portion of the radiator through the conduit 5 will pass through the central opening 12 and through the tubular extension 15.

The copper tube extends downwardly adjacent the forward end of the engine and is then directed rearwardly as shown at 16 in a substantially horizontal plane. The tube is then disposed downwardly as shown at 17 and communicates with a carburetor 3 for the purposes hereinafter to be more fully described. The horizontally disposed portion 16 of the copper pipe 10 is provided with a branch pipe 18 and the same has its lower end disposed within the intake manifold 2 in a manner clearly illustrated in Figure 1 of the drawing.

Arranged within the casing 6 are the bafiie plates 19 and the same are preferably arranged in staggered relation in the manner more clearly illustrated in Figure 3. The bottom of the casing is further provided with air openings 20 for the purpose of'admitting air to the casing whereby the same may come in contact with the vapor which is given off by the Water in the radiator it in the manner well known in the art.

The use of my humidifier attachment may be briefly stated as follows: The vapor from the radiator will pass upwardly through the tubular extension 7 into the, casing and around the baffle plates to the top of the ma ingwhen-the same will be forced into'the upper end of the copper pipe 10. Air'will be admitted through the openings 20 in the bottom of the casing and Will com-ingle with the vapor and will also'be admitted into the upper end of the copper pipe 10 where'the same comes in contact with the vapors so that a supply of moistened airisdelivered through medium of the-branch pipe 18. into the intake.

manifold 2;; In this manner a supply of moistened air'will come in contact with the charge previous to the delivery of the same to the cylinder and will furtheradd in the efliciency of the explosion of" the charge tl'i'ereby reducing the consumption of fuel as wellas tending to. reduce the collection of carbon in the cylinders.

The simplicity of my humidifier attachment enables the same to be readily and easily installed upon an automobile and will not interfere wi-th the operation, thereof or require the material alteration of the several parts thereof. Furthermore an attachment of this character will at all times be positive and efficient in its operation and the provi sion of the baflie plates within the casing will prevent any foreign substance such as dirt or the like from passing into the copper pipe together with the air and steam which is delivered thereto.

lVhile I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to without departing from'the spirit ofthe invention and the scope of the appended claim. 1

Having thus described my invention, what I claim is In combination with an internal combustion engine and a radiator associated therewith, a conduit extending from the radiator, a fitting between said conduit and said engine forming a connection between the engine and the radiator, a casing having bafile' plates arranged in staggered relation therein mounted on the radiatorand communicatlng therewith to receive the vapors therefrom,
